Sieghart and Jin both have a bar, on Sieghart it's called Berserk Bar while on Jin is called the Chi Bar...

I prefer Sieghart since:

*Stats are almost like my beloved elesis...*Skills are really cool, like Ares's 1st skill, it's just like Aegis Knight's Divine Slash...*Its 4th job is just like an exact replica of Cloud Strife (Dissidia, Final Fantasy VII)

Some preferred Jin because:

*High Defense and High Vitality*Grabs are really annoying, specifically Asura and Shisa (Champion)*Burning Mode makes him somehow invincible to some attacks and skills...
